A photopolymerized composite hydrogel and surgical implanting tool for a nucleus pulposus replacement.
Nucleus pulposus replacements have been subjected to highly controversial discussions over the last 40 years. Their use has not yet resulted in a positive outcome to treat herniated disc or degenerated disc disease. The main reason is that not a single implant or tissue replacement was able to withstand the loads within an intervertebral disc. Here, we report on the development of a photo-polym...
متن کاملNovel Hydrogel for the Replacement of the Nucleus Pulposus
INTRODUCTION Back pain induced by the degeneration of the hydrogel core of the intervertebral disc, the nucleus pulposus (NP) surrounded by the annulus fibrosus (AF), is currently a major public health issue. Different treating approaches exist such as vertebral fusion and total disc replacement with for example a SB Charité Prosthesis. However, recent trends in surgery are shifting towards pre...
متن کاملNanofibrillated cellulose composite hydrogel for the replacement of the nucleus pulposus.
The swelling and compressive mechanical behavior as well as the morphology and biocompatibility of composite hydrogels based on Tween® 20 trimethacrylate (T3), N-vinyl-2-pyrrolidone (NVP) and nanofibrillated cellulose (NFC) were assessed in the present study. The chemical structure of T3 was verified by Fourier transform infrared spectroscopy and proton nuclear magnetic resonance, and the degre...
متن کاملInjectable laminin-functionalized hydrogel for nucleus pulposus regeneration.
Cell delivery to the pathological intervertebral disc (IVD) has significant therapeutic potential for enhancing IVD regeneration. The development of injectable biomaterials that retain delivered cells, promote cell survival, and maintain or promote an NP cell phenotype in vivo remains a significant challenge. Previous studies have demonstrated NP cell - laminin interactions in the nucleus pulpo...
متن کاملFunctional compressive mechanics of a PVA/PVP nucleus pulposus replacement.
Emerging techniques as an alternative to the current treatments of lower back pain include nucleus replacement by an artificial material, which aims to relieve pain and restore the normal spinal motion. The compressive mechanical behavior of the PVA/PVP hydrogel nucleus implant was assessed in the present study. PVA/PVP hydrogels were made with various PVP concentrations. The hydrogels were loa...
